So, if the constant is constant, like PI, Gravity on earth, the speed of light in a vacuum, then its OK to capitalize it, but if the constant is line length, page length, or number of connections allowed, then its not really a constant, so it should not be in all caps. I can deal with something like that.
I'm still trying to get myself out of Hungarian notation and inital caps for functions.
I'm rather pleasantly surprised with the style guide. I've developed my own style over these many years of coding, and the only real eye-opener was spaces around identifiers, but it makes sense when you need to search for a variable.
